5. INSTALLATION
Unless otherwise specied, all measurements are expressed in millimetres (mm).
5.1 Preliminary checks
Check that the structure is sufciently rugged and that the hinge pivots are properly lubricated. Provide an
opening and closing stop.
5.2 Geared motor installation
Check the installation measurements on the basis of the distance between the hinge of the door wing and the
corner of the pillar [C] and of the desired opening angle [D].
The installation measurements indicated in the table allow you to choose the values of [A] and [B] on the basis
of the desired opening angle and in relation to the on site spaces and overall dimensions.
NOTE: The measurements [A] and [B] must be the same, in order to have a regular moviment.
Increasing [A] decreases the coming up speed during opening.
Increasing [B] decreases the coming up speed during closing and improves burglar-proong.
Reducing [B] increases the extent of gate opening.
Measurements [A] and [B] must in any case be compatible with the useful travel of the piston so that; if [A] is
increased, [B] must be decreased and vice versa.
